SClSSORS-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 604,118, dated May 17,1898.

Application iiled January 6, l 89 8 To cir/ZZ whom it may concern:

Be it known that I, HANS CHRISTIAN LAU- sEN, acitizen of the UnitedStates, residing at Newman,in the county of Stanislaus and State ofCalifornia, have invented certain new and useful Improvements inScissors-Sharpeners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of this invention is to provide an inexpensive device by theuse of which unskilled persons may quickly and perfectly sharpenordinary scissors or shears.

To this end an adjustable blade-holder clamp is pivoted -in position tocarry the blade back and forth over a suitable plane-facedabrading-block whose working face makes a constant angle with theinclined plane inner face of the blade.

The invention will be readily understood by the accompanying drawings,in which- Figure l is a perspective view of the device with a blade heldin position thereby. Fig. 2 is a section at 2 2, Fig. l. Fig. 3 is anenlarged section at 3 3, Fig. 1.

In the views, A,represents a plane-faced abrading-block, of stone,ernery, or the like, set centrally in abarB, which may be of wood,preferably having one end formed into a handle B. The upper face of theblock preferably projects slightly above the upper parallel plane faceof the bar. Upon this face of the bar, near the end opposite the handle,is pivoted a triangular metal plate C, which rests upon the bars facearound the pivot D, while the part extending over the block is raisedabove the plane of the latter. That maginal portion of the plate whichis opposite the pivot is oblique to the axis of the bar and is bentsharply downward at an angle with the face of the bar to form a broadplane lip E, against which the plane face of the blade F to be operatedupon rests. The blade is firmly held against thislip bya spring i G,secured to the plate bya screw H H, passv ing through a slot in thespring into the plate C. The plate is centrally cut away a little in therear of this screw, and the spring passes downward through the openingand bends forward beneath the plate and then downward, preferably insuch manner as to form bearings at I I in a plane approximately par-Serial No. 665,837. (No model.)

allel to the plane of the lip, and hence adapted 5 5 to meet the bladeat points not far from its margins, respectively. Now this spring beingadjusted and fixed in place by the screw the blade may be pushed in fromeither direction between it and the lip, the spring yielding enough toaccommodate small variations in the size of blades, where it is heldwith sufficient rigidity for all practical purposes at the proper anglewith the face of the abrading-block. The plate itself is so connected tothe bar that its blade-carrying end may move toward and away from theblock far enough to accommodate various widths of blades. Should anyblade vary too much from the thickness for which the spring is set, thelatter may be adjusted by means of the screw passing through its slot,as already explained.

The blade having been inserted from one end or the other, according toits bevel, the arm is pressed toward the block with any desired degreeof force and oscillated upon its pivot through an arc sufficient tobring all parts of the cutting edge in contact with the block, and thusthe blade is quickly and accurately ground or sharpened.

It is obvious that blocks differing in nneness may be provided andinterchanged at will and also that the exact construction need not befollowed.

What I claim isl. The combination with a bar and an abrading-block fixedthereto, of a plate pivoted at one end to the bar to swing in a planeparallel to the working face of the block and having a projectionvextending toward the working face of the block, and means for clampingagainst said projection a blade to be sharpened.

2. The combination with the handled bar, of the abrading-block securedin the middle portion of the bar, the plate pivoted tothe bar at the endopposite the handle and provided with the lip, and the adjustable springadapted to coact with said lip in holding a blade, substantially as setforth.

In testimony whereof I affix my signature in presence of two witnesses.

HANS CHRISTIAN LAUSEN.
